A sequential explanatory mixed method study of maternal and fetal outcome in gestational diabetes mellitus using Diabetes in Pregnancy Study Group India (DIPSI) test in Puducherry.

BACKGROUND

Gestational diabetes mellitus in pregnancy is associated with polyhydramnios, macrosomia, and shoulder dystocia, and it also increases maternal and perinatal mortality.

METHODS

This sequential explanatory mixed-method study was conducted for six months. All the pregnant women attending the outpatient department of the Obstetrics and Gynaecology Department at 24-28 weeks of gestation were subjected to universal screening with 75 gms of glucose and 2 hours of plasma glucose >140 mgs% is taken for diagnosis (according to DIPSI guidelines). After diagnosis, they were subjected to an HbA1c test. Women with HbA1c is >6.5% were excluded from the study. If pregnant women are screened negative by the DIPSI test, the test was repeated in the third trimester (32-34 weeks of gestation). Chi-square tests were used to find out the test of association for quantitative data and manual content analysis was performed for qualitative data.

RESULTS

DIPSI test was found to decrease the adverse maternal and neonatal outcome by early screening and management. The stakeholders' perspectives identified by key informant interview were improper knowledge and awareness about the testing and others were anxiety and fear associated with the testing procedure.

CONCLUSIONS

As DIPSI test is an effective single step in screening and diagnostic test, hence all pregnant mothers should undergo this glucose challenge test in their antenatal visits.
